4 Claims.

This invention relates to an'advertising display device and more particularly to a device for visibly demonstrating the physical characteristics of a tenacious, viscous or adhesive material.

It is well known that animated displays have a particularly strong appeal to the public, and it is an object of the present invention-to provide an animated display wherein a tenacious, viscous or adhesive material such, for example, as a heavy lubricating grease is Worked or agitated in such manner as to visibly display certain of its physical characteristics.

For a better understanding of the invention reference may be had to the accompanying drawing, in which:

Fig. l is a view in vertical section of a display device embodying the present invention;

Fig. 2 isa view taken on the line 2--2 of Fig. 1 and showing the mechanism employed for actuating the display device; and

Fig. 3 is an enlarged sectional plan View taken on the line 3--3 of Fig. 1.

In the drawing there is shown a receptacle or container It which may be of any desired shape or size and which is adapted to contain the material the physical characteristics of which it is desired to display. The receptacle It may be supported in any desired way but in theV present embodiment of the invention it is shown disposed upon the upper end of a tubular standard I2 the lower end of which is supported in a base member I4 which in turn is preferably secured to the top I6 of a table, cabinet or the like.

The base of the receptacle I0, as well as the top I6 of the table or cabinet, are provided with openings through which extends an operating shaft I8. A disc is secured to the upper end of shaft I8 and is adapted to be seated in the receptacle I when the shaft is in its lowermost position. Shaft I8 extends through the opening in the base of receptacle I0, through the tubular standard I2, the base member I4 and through the opening provided in the top I6 of the table or cabinet.

The lower end of shaft I8 is threadedly connected to a socket 22 which is adapted to contain a ball 24. The ball 24 is secured to one end of a connecting rod 26 and is maintained in position within the socket 22 by a gland 28. The opposite end of the connecting rod 26 is provided with a bushing 30 which engages a crank pin 32 on a concentric disc434. The disc 34 is secured to a rotatable shaft 36 which is mounted in a suitable bearing 38 and which is` operated by an electric motor 40 through reduction gears 42 and 44.

Shaft I8' is provided with a spiral groove 46. A guide pin or screw 4S extends` through a suitable opening in the base member i4 and its inner end is adapted to engage in the groove 46 so that during the reciprocation of the shaft an oscillating movement will be simultaneously produced.

In practice the device is set up with the receptacle lil arranged at a convenient height above the table or cabinet top IE and with the operating mechanism concealed from view below. The elec- 10 tric motor 43 is operated from any suitable source of electric supply and through the medium of the reduction gears 42 and 44 the disc 34 is rotated at a relatively slow speed. The rotation of the disc 34, through the action of. the connecting rod 15 25, produces a reciprocating and oscillating movement of the shaft I8. A similar movement is imparted to the disc 2li which is connected to the upper end of the shaft I8.

I'hus it will be seen that if the receptacle I0 20 is filled with the material the physical properties of Which are to be visibly vdemonstrated and if that material is of a tenacious, viscous or adhesive character such, for example, as a viscous grease, it will adhere to the lower face of the disc 25 2i) as the latter is reciprocated and oscillated. A person observing the display will see the mass of material subjected to a continuous succession of movements which rst Vdraw it out and twist it and then compress the mass together again. A material of good body and of an adhesive or Viscous character will withstand these continuous operations indefinitely without breaking the continuity of the mass.

1 claim:

1. An advertising display device for visibly demonstrating the physical characteristics. of a viscous or adhesive material, comprising a container for the material, a disc normally resting upon the surface of the material in the container, and means for moving the disc upwardly at periodic intervals and for rotating it as it is raised to visibly demonstrate the ability of the material to adhere to both the container and the disc during 45 the raising and rotation of the disc.

2. An advertising display `device for visibly demonstrating the physical characteristics of a viscous 0r adhesive material, comprising a disc normally resting upon and adapted to adhere to the surface of a body of the material, ano1 means for imparting a reciprocating movement to the disc to move it at predetermined intervals away from the body rof material for visibly demonstrating the ability of the material to adhere to the disc and to be drawn out Without breaking the continuity of the mass.

3. An advertising display device for visibly demonstrating the physical characteristics of a viscous or adhesive material, comprising a disc normally resting upon and adapted to adhere to the surface of a body of material, a rod attached at one end to said disc, means for reciprocating said rod to move said disc to and away from the Viscous material, and means for oscillatingv said rod during the reciprocation thereof so that the material adhering to the disc is alternately drawnY .out and twisted and then compressed without at any time breaking the continuity of the mass.

4. An advertising display device for visibly demonstrating the physical characteristics of a viscous or adhesive material comprising a container for the material, a disc normally resting upon and adapted to adhere to the surface of the material, and means for periodicallyV eiecting relative movement between the container and the disc to cause the material to be stretched out between the container and the disc Without breaking the continuity of the material.
